Working Memory, and Getting Things Off Your Head

Excellent, excellent email here from Cristian Strat in response to last week's newsletter, "GSV#9: Get Things Off Your Head."

Here's Cristian -

Hey Sebastian! I was thinking about the impact of getting things off your head.

I'm not an expert but I was reading about Working Memory and the correlation between that and your general level of fluid intelligence and attention level. Apparently people can only hold about 5-7 bits of information at once for thought manipulations and reasoning. Apparently, being able to hold a few more things in your working memory makes a dramatic improvement in your thinking abilities. Consequently, a smaller capacity will make for an inferior thought process.

Now, when you try to keep things in your head (like "Don't forget to call mom at 4pm") while working, you effectively operate with a lower capacity Working Memory. You constantly have to refresh "Don't forget to call mom at 4pm". As an experiment, try to remember a 4 digit number while working on something.

Recording Aperture when using Legacy lens

On The Nosy Moth

As a part of my LMMM challenge, I am using a legacy Konica Hexanon AR 50mm f1.7 lens via adapter with my Olympus Pen E-P5. This lens has a manual aperture ring on the lens barrel. The camera, also does not recognize the lens - because of which the EXIF information in the photographs do not contain aperture information.

As a part of LMMM, I wanted to try to record the aperture information somehow, so I can embed that information in my photographs as a part of my post-processing workflow. Here is how the information is embedded in the photograph EXIF via Lightroom: Adding Legacy Lens EXIF Info for Lightroom metadata.

But the question remained on how to capture that information when taking photographs. The method of writing down the photograph number and corresponding aperture using pen/paper, for each photograph seemed too cumbersome. The other option recommended a lot is to use a voice-recorder (or teh voice recorder option in your phone) which also seemed cumbersome - this info is stored on another device! I found my answer on this forum thread: Olympus cameras offer the option to embed audio when reviewing images. * In playback mode, when reviewing the image, * press \'OK\', * then press the \'microphone\', * and record voice. This is stored as a .wav file with the same filename as the image being reviewed. When you review the image now, you can just play your recorded voice.

So my workflow is now like this: At the beginning of the day * Format memory Card (assuming you have downloaded all the images from your memory card) * Take first photograph * Review this photograph and voice-record aperture information. * Continue to take photographs * Every time aperture is changed, only then for that photograph, review that photograph and record aperture.

The aperture information of a photograph is the same as the aperture in the previous photograph unless it has a .wav file with aperture information in it. And this system is working great for now!
